1. Convert from txt to yaml
2. Drop "Driver for" from the title
3. Document "#phy-cells"
4. Fix example node name (noticed by dt_binding_check)
5. Add #include to example (noticed by dt_binding_check)
6. Specify license

I think this should go through linux-phy tree. Kishon, Vinod, can you
take this patch?
This patch generates a false positive checkpatch.pl warning [0].
Please ignore:
WARNING: DT binding docs and includes should be a separate patch. See: Documentation/devicetree/bindings/submitting-patches.rst
[0] https://lkml.org/lkml/2020/2/18/1084
Same thing here.
Kishon, Vinod: I sent this patch back in December, it was Reviewed-by
Rob, but never accepted.
Could you push this patch to the linux-phy.git?

-Driver for Broadcom Northstar USB 2.0 PHY

-Required properties:

-- reg: iomem address range of DMU (Device Management Unit)
-- reg-names: "dmu", the only needed & supported reg right now
-- clocks: USB PHY reference clock

-To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
